For safety reasons, we recommend not screwing the CO2 cartridge into the inflator head until needed in order to prevent CO2 being dispensed in storage / transport.
One you have achieved the required tyre pressure, any residual gas in the cartridge should be fully emptied for safety reasons.
Most threadless presta valves have a small screw / threaded section at the very top of the valve stem which normally works with our CO2 inflator. If you purchase the inflator and things aren’t compatible for some reason, then send us a message and we’ll ensure we make things right for you.
The CO2 inflator is compatible with both Presta and Schrader valves, as the force of the gas expelled from the inflator head forces the valve open, no matter which type it is.
Yes, however you will need to ensure that the removable element is fully screwed into the valve so that it does not become loose under the pressure of the gas and potentially waste any of the content of your cartridge.
The tyre pressure that you can achieve with the inflator depends on what size cartridge you use, and the type of tyre that you have. Please refer to the below chart to find out what pressures can be achieved. Please bear in mind that CO2 gas slowly dissipates through rubber over time. As such, you will find that the normal tyre pressure will reduce slightly in the following day as the gas dissipates. We therefore recommend you refill your tyres with normal air using a conventional bike pump (mini or floor) once you get home after your ride.
The CO2 inflator head supplied with the red foam sleeve fits ANY size of threaded CO2 cartridge (12g, 16g, 20g & 25g). However, please be aware that the red foam sleeve is designed to only fit over a 16g threaded CO2 cartridge. The CO2 inflator with metal storage canister is designed for 12g or 16g threaded CO2 cartridges, both can be stored in the storage canister before or after use.
A spare o-ring is a potential replacement for both of the o-rings that are inside the inflator (the one in the nozzle that connects to the tyre valve, and the one in the end that you screw the co2 cartridge into). If either of the current ones wears out or falls out for some reason, you just need to insert the new one. You will need to poke it down into the relevant end of the inflator to position it.

The Allen Key Set is manufactured in Taiwan.
